I've been using my car's navigation system for two years and it has always worked well.
However, about two weeks ago, I noticed that the navigation no longer displays or calculates routes based on real-time traffic conditions. While I can see the color changes indicating traffic flow on the map, these traffic conditions are not reflected on the navigation's route map. Moreover, the recommended best routes are now based solely on distance, without considering the traffic situation.
Has anyone else experienced this issue?

 

Are all your subscriptions still ACTIVE ?

YMMV,

if I understand this correctly, navigation function doesn’t require any subscription. Also, I didn’t see any subscription option in my car

 

Navigation itself is a subscription service and part of the Drive Connect subscription. If you got the large screen, you get a 3 year trial of Drive Connect. You would see your subscriptions in your Lexus app.
So if you're still seeing navigation at all, it's still active.
As far as traffic issues, maybe the Lexus server is having some backend issues with traffic info? Not sure.

 

I'm also guessing it's the server's issue, and this is why I posted this, hoping to find other people with the same issue

 

navigation maps are on the hard drive. Updates of traffic are a subscription service. Though they work together, they are separate. This is why I like google maps, it's updated constantly with no fee. Please check your Drive connect account and let us know what you find.

 

Thank you for your reminder, which alerted me to the existence of subscriptions associated with my car. However, upon checking, I found that all my subscriptions are shown as active on that page.

 

Navigation maps are not on the hard drive for the Lexus Interface. This is cloud navigation system. The maps are cached on the device, but they are updated into the cache from time-to-time. It is different from the Lexus Enform system where the maps are loaded in the car and no updates are in the system. Unless you map to get the maps updated.

 

there is a cloud module update to fix this .

the built in integrated music would fail to connect at times as well as the real-time traffic would fail to update .

i had the same issue and the update solved it .

if can only be done by the dealer

 

Is this true across the board with Lexus? I was under the impression they went to a model where all the map data is downloaded as it’s needed.

I just bought a 2025 RX450h+. When I opted out of the master data sharing, my car turned very dumb - no map showed at all, and the time was wrong!

Depends on what infotainment you have. Older systems are on a SD card. Lexus interface in Americas uses cloud base navigation. I believe it's a little different in Europe.

 

Just curious. Is there a reason people buy updates for car nav systems when they can use their phone along with apple play or android auto?

 

I really don't know of any upside except if you don't own a mobile phone or don't want to bother connecting it to your car's infotainment system. I believe older systems that have maps imbedded into it with a hard drive are the only example. These systems didn't usually play nice with your phone to allow phone imagery to 'cast' onto your centre screen. You have no choice but to use the car's internal setup or mount your phone into a holder on windshied to view your map on your phone.

This early setup would only update the map with a purchased map update usually through your dealer. Pretty basic stuff. I have an old Tom Tom gps map and I had to constantly go online to update it's mapping info then reinstall it in my car.

 

My phone is connected via bluetooth to my infotainment system and I use Apple Car Play to view the iphone's navigation screen on the car's screen. No need to mount my phone, just leave it in my pocket. It's the only way to go.

 

I believe Apple Carplay uses bluetooth for it's initial connection. After that it uses WiFi to transmit audio and visual data to the lexus system.
